Description

WINDSHIELD WIPER WITH WATER SUPPLY MEANS

DESCRIPTION: This invention conserns, α good quality rubber windshield wiper multiblade, which cleans and simultaneously sprays water onto the windshield for use on all types of vehicles. The length of the blade is analogous to the wiper arm which will be used and the bulk of the vehicle. METAL BACKBONE ROD: (see sketches 1 and 2, no.l ) It will be used in conjunction with the multiblade (for strength) on the wiper arm. For a wiper arm, one of those available on the market, will be used. The rod can be made of a strong plastic material too or of stainless steel or any other metal. It is 1 mm thick and as wide as the head of the multiblade. THE HEAD: (see sketches 1 and 2, no.2) The 'Head' is one body with the rest of the multiblade. It carries the 'fitting grooves' (see sketches 1 and 2, no.3) of the multiblade, for fitting onto the arm along its entire length. The head is 12mm wide (or as wide as is necessary to fit on the arm, depending on the type of arm used, and also on the use intended for the multiblade and the needs of the particular vehicle. On big vehicles the multiblade will be bigger and of a heavier construction and thus the head will be wider. The head's width is narrower than the Body (see sketches 1 and 2, no.4) of the 'Multi blade'. Its height is 6 mm (or again analogous to the needs of the vehicle and type of arm used) .

FITTING GROOVES: (see sketches 1 and 2, no.3) They will be about 1 mm to 1 Pi mm wide and about 3mm deep. They are situated in the head (see sketches 1 and 2, no.2) and are used to fit the multi blade to the arm.

Again the dimensions given vary according to the arm used, the multi blade and the thickness of the 'metal backbone^' rod' (see sketches 1 and 2, no.1 ) to be used. BODY: (see sketches 1 and 2, no.4) It will be round in shape and of 2cm diameter. In its core from one end to the other it carries the 'water tunnel' (see sketches 1 and 2, no.6). It also carries the three 'lower water pores' (see sketches 1 and 2, no.7), the 'main water pore' (see sketch2, no.10). The 'water muzzle' (see sketch 2, no.8) fits into the 'water supply pore' (see sketches 1 and 2, no.6).

Around the body, on its outside perimeter and along its length from one end to the other the 'cleaning legs' (see sketches 1 and 2, no.5) are situated.

The 'water supply pore' (see sketches 1 and 2, no.6) will be situated at the bottom of the multiblade.

The 'lower water pores' (see sketches 1 and 2, no.7) will be situated at the bottom surface of the multi blade, and will cut the 'cleaning legs' (see sketches 1 and 2, no.5), so as to have direct access to the windshield. The 'water tunnel' (see sketches 1 and 2, no.6) will be 5mm in diameter. The 'lower water pores' (see sketches 1 and 2, no.7) will be 3mm in diameter and the 'water supply pore' (see sketches 1 and 2, no.6) will be 5 mm in diameter.

The 'cleaning legs' will be 2mm at the base and their top will be sharp and 3mm high with a pyramidal shape! At the top end of the multi blade as it is placed on the windshield, the 'main water pore' (see sketch 2, no.9) is situated, which is the natural ending of the 'water tunnel' and will be 5mm in diameter and will have fitted to it the 'water spray nozzle' (see sketch 2, no.10) .

CLEANING .LEGS: (see sketches 1 and 2, no.5) There are going to be about 23 cleaning legs around the body from one side of the head to the other. As many legs as will be in contact with the windshield when the wiper arm is working, will clean the glass faster and more effectively, since at least 3 of them will contact the glass and their action will be triple (or even quadruple) . The cleaning legs will be 2mm wide at their base and their top will be sharp 3mm high and will have a pyramidal shape. They will extend from one end of the multiblade to the other and those of them that are not used for cleaning have been put there for appearance purposes, for beauty and a sporty look! The cleaning of the windshield will be done fast and effectively and phenomena like unclean lines on the windshield will be avoided since three of even four cleaning legs is virtually impossible to be cut at the same exact point.

WATER TUNNEL: (see sketches 1 and 2, no.ό) It is located at the core of the body (see sketches 1 and 2, no.4). It extends from one end of the multiblade to the other. It is 5mm in diameter.

As its top end the 'water spraying nozzle' is fitted (see sketches 1 and 2, no.10).

It also carries the 'lower water pores' (see sketches 1 and 2, no.7) and the 'water supply pores' (see sketches 1 and 2, no.ό) at it lower end.

LOWER WATER PORES: (see sketches 1 and 2, no.7) They are situated at the lower surface of the multiblade. See also par.4 above. Their use is to eject water onto the windshield. The water is supplied to them through the 'water tunnel' (see sketches 1 nad

2, no.ό) and the 'muzzle' (see sketch 2, no.8). Their diameter is 2mm. (It is understood that they can be wider or narrower depending on how powerful is the motor, pumping the water to the multiblade.

WATER MUZZLE: (see sketch 2, no.8) A plastic accessory. It will fit into the 'water supply pore' (see sketches 1 and 2, no.ό) . Its diameter will be 5mm at the 'upper part' (see sketch 2, no.8a) onto which the water hose will fit (see sketch 2, no.10). This upper part will be rough outside as glass paper, so that the water hose cannot be detached easily. It can instead carry sharp anchors (see sketch 2, no.δb) around it, with a downward inclination. Its 'lower part' (see sketch 2, no.δc) will be 4mm in diameter and bears around it anchors of 1 mm width and slanted upwards, so that when it is inserted into the water tunnel (see sketches 1 and 2, no.6), fits perfectly without any leak.

MAIN WATER PORE: (see sketches 1 and 2, no.9) It is the upper water tunnel opening of the 'water tunnel' (see sketches 1 and 2, no.ό) . It has 5mm in diameter and the 'water spraying nozzle'

(see sketch 2, no.10), is fitted into it. WATER SPRAYING NOZZLE: (see sketch 2, no.10) It is made of a strong plastic material. It has a water tube of 3mm in diameter (see sketch 2, no.10a), with holding 'anchors' (see sketch 2, no.10b) of 1 .5mm width. The nozzle fits into the 'main water pore' (see sketch 2, no.9) in the same way the 'water muzzle' fits into the water introduction pore (see sketch 2, no.8).

The nozzle will carry outside the 'main water pore' (see sketch 2, no.9) an inverted V shaped tent like structure (see sketch 2, no.10(c) which is one body with the rest of the nozzle. It has a downward slant towards the windshield, so that when the water from the 'water tunnel' (see sketches 1 and 2, no.ό) through the tube, strikes it, the water will be directed towards the windshield. WATER HOSE: (see sketch 2, no.l 1 ) It is made of a pliable plastic or elastic material. Its diameter will be 5mm. It fits onto the 'upper part' (see sketch 2, no.8a ) of the 'water muzzle' (see sketch 2, no.8).

Claims

1 . A multiblade windshield wiper. Bears about 23 cleaning legs (see sketches 1 and 2, no.5) around its 'Body' (see sketches 1 and 2, no.4), which legs, when the arm is moving right and left, the cleaning legs (at least 3 of them in each side) will contact the windshield and with their sharp edges will clean it, faster and better than any other wiper.

2. The 'water muzzle' (see sketch 2, no.8) will fit into the 'water introduction pore' (see sketches 1 and 2, no.ό) firmly and tightly. Onto its upper part, the 'water hose' (see sketch 2, no.10) will fit. 3. The water hose (see sketch 2, no.1 1 ) will fit onto the upper part of the 'water muzzle' (see sketch 2, no.8) water-tightly. For safety it will be secured to the wiper blade arm.

4. The 'metal backbone rod' (see sketches 1 and 2, no.l ) will give strength and stability to the 'Body' (see sketches 1 and 2, no.4) of the blade and the whole blade.

Instead of one metal rod, two smaller metal rods can be used which will be inserted into the 'fitting grooves' (see sketches 1 and 2, no.3) (like the common wiper blades in the market) .

5. The Multiblade makes unnecessary the mechanism of jetting water onto the windshield so that it helps the car manufacturer save money. ό. The multiblade cleans the windshield glass in 1 /3 of the time of the common wiper blade. 7. The multiblade cleans better leaving no traces or lines of unclean glass. 8. With the use of the multiblade the water jetting on the windshield does not wet the roof of the car or its sides, which is common with the usual water jetting mechanism, which very often sprays water out of control. 9. Also the phenomena of wetting passengers trying to get into the car when the water jetting mechanism is worked and the spraying with water of following cars, when the car is traveling are completely avoided.

10. The water jetting system with the use of the multiblade will not block easily since the diameter of the 'water pores' (see sketches 1 and 2, no.7) is comparatively large.

1 1 . The multiblade will have a longer life than common wiper blades so the car owner will save money and trouble.

12. The multiblade will be generally stouter than the common wiper blade, it will have a better sporty appearance and will attract the buyer.
